ar, you should understand the concept of mpi intercomms. a good starting point could be the standard: http://www.mpi-forum.org/docs/mpi-11-html/node111.html by the way: * your one_int is never intitialized * i don't know if the MPI_COMM_SELF is the right comm for the MPI_COMM_SPAWN by bert we

[OMPI users] Why should the attached code wait on MPI_Bcast

Please see attached source file. According to my understanding of MPI_Comm_spawn(), the intercommunicator returned is the same as it is returned by MPI_Comm_get_parent() in the spawned processes. I am assuming that there is one intercommunicator which contains all the (spawned) child processes as

[OMPI users] readline and mpirun

When I run my MPI enabled application via mpirun, my application command-prompt looses its readline editing capability. I was wondering if there is workaround. Thanks. Saadat.

known problem with comm_spawn from a singleton (i.e., if you just did a.outinstead of mpirun —np 1 a.out) - the errors look somewhat like what you are showing here, hence our curiousity. Thanks Ralph On 7/6/06 3:12 PM, "s anwar" wrote: Ralph: I am using Fedora Core 4 (Linux turk

What configuration do I need to run child/slave MPI processes created via MPI_Comm_spawn on another machine. Thanks. Saadat.

[OMPI users] MPI_Comm_spawn

I have a very simple program which spawns a number of slaves. I am getting erratic results from this program. It seems that all the slave processes are spawned but not all of them complete the MPI_Init() before the main program ends. In addition I get the following error messages for which I haven
